Blue screening while playing any game, but mostly WoW

Okay, so on monday my computer started blue screening randomly. I don't think its heat related as according to speed fan all my CPU temps are below 100 degrees when it happens.

It happens at random at this point. Sometimes i can play for hours, then other times it happens every 2 minutes to the point of frustration.

There have been no hardware changes and I didn't install anything on monday, and i even tried a system restore to a day before that when the machine had no such problems to no avail. I have anti-virus installed and am up to date on its updates.

When my system reboots I get a message from Windows saying it recovered from a serious error. The error code information that it wants to send off to Microsoft, which is can't because it says there is an error in the file, is as follows:

1. Go to www.memtest.org and download the latest ISO version. It is free and perfectly safe.

2. Burn to a CD.

3. Place CD in your drive and reboot with CD in drive. (You might have to place your drive as first bootable in your BIOS) The test will take over.

4. Let it run for a LONG time. The rule is a minimum of 7 Passes. There are 8 individual tests per Pass. Many people will start this test before going to bed and check it the next day.

5. If you have errors you have corrupted memory and it needs to be replaced.

6. Also, with errors you need to run this test per stick of RAM. Take out one and run the test. Then take that one out and put the other in and run the test. If you start getting errors before 7 Passes you know that stick is corrupted and you don’t need to run the test any further on that stick.
